BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates generally to hand-held electronic touch screen devices such as smart phones, electronic book readers, and tablet personal computers, and more particularly to augmenting these devices with various external manual hard buttons and/or actuators and indicators for controlling remote devices.

2. Background Art

Touch screen smart phones, electronic book (eBook) readers, and tablet computers have become ubiquitous. Many such touch screen devices employ a touch screen interface along with generic manual controls and/or actuators, while other touch screen devices employ a touch screen interface alone.

The generic manual controls employed on a touch screen device are typically configured to operate of the touch screen device itself or configured to operate specific applications executing on the touch screen device, and are unavailable for controlling remote devices.

Although some touch screen interfaces are relatively sophisticated and incorporate advanced touch screen features such a multi-touch and gesturing features, touch screen interfaces are simply not appropriate for all applications. For example, existing touch screen devices do not provide dedicated volume control buttons that can be used to control the volume of remote devices.

While such dedicated buttons for controlling remote devices could be provided in the form of soft buttons via a graphical user interface on the touch screen device, such soft buttons would occupy a significant amount of on-screen area, and thus reduce the on-screen area available for other applications.

Further, using a touch screen interface for repetitive remote control functions, such as changing channels (i.e., channel surfing), for example, is awkward and uncomfortable, provides significant stress to a user's fingers, and can cause repetitive stress injuries (RSI). Despite these drawbacks, because of the graphic flexibility of the touch screen interface, remote controls are increasingly being equipped solely with touch screens.

Additionally, although users typically desire a remote control with a large display, the size of the touch screen is limited because the user needs to be able to hold the remote with one hand and input commands with the other, free hand. Remote controls with large touch screens, such as with tablet remote controls, are difficult to hold with one hand while inputting commands with the other hand. Typically, these large devices must be placed on a table or other surface to be operated properly. Users have a natural inclination to grasp tablet devices with each hand in an open precision grip, with the user's thumb finger above the top side of the tablet and the remaining four digit fingers on the bottom side supporting the tablet.

In view of the above-described issues, there is a need to integrate a relatively low-cost portable smart touch screen device with a specialized control device employing hard buttons to produce a remote control with the graphic flexibility of a touch screen interface and the ergonomic benefits of physical control buttons, and which may be easily operated while being held naturally by a user.

Additionally, there is a need for such a specialized control device to include a dedicated power supply and independent wireless networking capability in order to avoid usage limitations based on the limitations of the associated touch screen device.

MODE(S) FOR CARRYING OUT THE INVENTION

The present invention involves augmenting a portable smart touch panel with an external control system by disposing the portable smart touch panel device, such as an Apple® iPad™ tablet computer, an Apple® IPhone®, or a Motorola® DROID® phone, or the like, for example, within a protective enclosure (e.g., clam shell) that includes one or more dedicated hard buttons and one or more means for wireless communication, and thereby forming a remote control device.

The remote control device accepts user input and is capable of transmitting control commands to a plurality of controllable devices, such as audio and video components, lighting controls, and HVAC controls. In one embodiment, the remote control device transmits control commands independent of whether or not the touch panel device is on, or a particular application is executing on the touch panel device. In another embodiment, the smart touch panel device executes an application that complements the intended end-use of the remote control, such as a graphic user interface that functions as a control panel for an office or home automation system or home theater.

The remote control, in various embodiments, utilizes communication methods known in the art to transmit control commands (e.g., key/button presses) either directly to the controllable devices or indirectly through an intermediate device. For example, the remote control may transmit control commands as infrared (IR) or wireless radio frequency (RF) signals.

Referring to FIG. 1, in one embodiment, an illustrative front view of a portable touch screen device 5 disposed within a protective clam shell enclosure 1 and thus forming a remote control device 3 is shown. The clam shell enclosure 1 includes a front clam shell portion 10 and a rear clam shell portion 20 (see FIG. 3). The front portion 10 of the enclosure 1 includes a viewing screen access opening 11 which is dimensioned and arranged to fit around the viewing screen of the touch screen device 5 so that the touch screen can be seen while disposed in the enclosure 1. The front portion 10 further includes dedicated hard buttons 31, 32, a five-way thumb pad 33, indicator lights 34, an external universal serial bus (USB) connector 13, and an infrared (IR) emitter 17. In other embodiments, more or less hard buttons, lights, and communication ports can be included. In addition to the dedicated hard buttons 31, 32, in various embodiments, the enclosure 1 includes one or more optical finger navigation buttons and/or trackballs.

Referring to FIG. 2, an illustrative perspective rear view of the portable touch screen device 5 and the inside of the front portion 10 of the clam shell enclosure 1 are shown An internal docking connector 12 is disposed on the inside surface of the front portion 10. The docking connector 12 is configured for electrically connecting/mating to a connector (not shown) disposed on the portable smart touch screen device 5 and enables a communication and power transfer path between the enclosure 1 and the touch screen device 5.

Referring to FIG. 3, an illustrative perspective rear view of the portable touch screen device 5, the front portion 10 and the rear portion 20 of the clam shell enclosure 1 are shown. The front portion 10 further includes an audio connector 14 disposed on an inside surface. The audio connector 14 is configured to electrically connect to a complementary audio port on the touch screen device 5. In some embodiments, speaker holes are disposed in an area of the enclosure 1 that is proximate to a speaker on the touch screen device 5 so that sound from the touch screen device can pass through the enclosure 1 without being muffled. The rear portion 20 includes a connector 21 that electrically mates with a docking station 2, as shown in FIG. 4. The docketing station 2 provides a means for charging rechargeable batteries disposed in the enclosure 1 and the touch screen device 5. The docking station 2 also provides a communication link with the office or home automation system or home theater (see FIG. 9), and is discussed in detail below.

The front portion 10 and the rear portion 20 engage each other along common mating edges and are held together using spring retention or pod clips (i.e., clips). The front portion 10 and the rear portion 20 are molded preferably of a high strength plastic material for both high impact strength and natural decorative effect. The clips are formed of high-strength stainless steel material for resilience and springiness. The front portion 10 and the rear portion 20 are thus tightly held together and securely hold the touch screen device 5 without the need for additional fasteners or connectors or adhesive. The enclosure 1 may be easily detached and interchanged with components of different colors and textures for aesthetic purposes, or for the servicing of components or batteries within the enclosure 1 or touch panel 5.

Referring to FIG. 4, as mentioned above, the rear portion 20 includes a connector 21 that electrically mates with the docking station 2. The docketing station 2 provides a means for charging rechargeable batteries disposed in the enclosure 1 and the touch screen device 5. The docking station 2 also provides a communication link with the office or home automation system, and is discussed in detail below. The docking station 2 further acts as a mounting stand capable of suspending the touch screen device 5 (enclosed in the enclosure 1) in space at one of a plurality of angles, which allows a user to view and operate the touch screen 5 easily.

Referring to FIG. 5, in one embodiment, a block diagram of a plurality of remote control devices 3 in communication with a home automation system 70 is shown. The home automation system 70 is in communication with, and controls, lighting 71, HVAC 72, security 73, a home theater system 77, and a home audio system 78. The home automation system 70 can be configured and controlled via a personal computer 105, a keypad 75, and/or, as described in detail below, the remote control device 3 via a wireless Wi-Fi gateway 76 and/or a wireless Zigbee gateway 76′, or the remote control device 3 disposed in the docking station 2, which is in wired communication with the home automation system 70. In some embodiments, the remote control device 3 can be used to connect to the internet 100 via the home automation system 70 through either wired or wireless communication. In other embodiments the wireless Wi-Fi gateway 76 and the wireless Zigbee gateway 76′ are combined into a single wireless gateway device.

Referring to FIG. 6, in one embodiment, an illustrative block diagram of the electronic components disposed in the clam shell enclosure 1 is shown. The electronic components disposed in the clam shell enclosure 1 include a processor 50, a memory 43, a USB switch 42, a power supply 45, the external docking connector 21, which includes connections for USB communication and power, and the internal docking connector 12, which also includes connections for USB communication and power.

The processor 50 includes general purpose input/output (GPIO) interfaces that are in communication with one or more keypad matrices, which are in communication with the hard buttons 31, 32, 33. The processor 50 further includes a USB interface in communication with the USB switch 42 via a USB wired connection 131. The processor 50 is also in communication with the indicator lights 34 and the memory 43 (e.g., RAM, ROM, EPROM). In other embodiments, the processor 50 includes an on-board memory. The USB switch 42, which is controlled by the processor 50, is in communication with the internal docking connector 12 via a USB wired connection 133, and the external docking connector 21 via a USB wired connection 132. The external docking connector 21 is also in communication with the power supply 45. In other embodiments, the USB interface on the processor 50 is a USB on-the-go (USB-OTG) interface.

The power supply 45 includes a rechargeable battery and a charging circuit known to those skilled in the art and supplies power to all the circuitry disposed in the clam shell enclosure 1. The power supply 45 (i.e., battery) can be recharged via the external docking connector 21 when connected to the docking station 2. The power supply 45 also allows a charging current from the docking station 2 (and passing through the external docking connector 21) to pass through to the internal docking connector 12 and charge a battery disposed in the portable touch screen device 5. Further, the power supply 45 can also draw power from the battery disposed in the portable touch screen device 5 (through the internal docking connector 12) to charge the battery in the power supply 45 and supply power to the circuitry disposed in the clam shell enclosure 1.

Still referring to FIG. 6, one part or component of a software application (first application component) for controlling a home or office automation system (e.g., automation system 70) is stored in the memory 43 or in a memory on the processor 50 and executes on the processor 50. Additionally, another part or component of the software application (second application component) for controlling the automation system 70 resides and executes on the portable touch screen device 5. The first and second components of the automation system control application execute independent of any other application that may be executing on the touch screen device 5. Further, the first and second application components execute independent of each other.

The first application component executing on the processor 50 interprets input from the hard buttons 31, 32, 33, converts the hard button actuations into digital signals, and transmits the input (digital signals) to the touch screen device 5 or directly to the automation system 70, as described below. In various embodiments, at least some of the hard buttons 31, 32, 33 are dedicated control buttons with fixed functions, such as volume up/down, channel up/down, lights on/off, home, guide, info, exit, and/or mute, for example. These hard buttons execute their respective control functions upon being pressed by a user regardless of the state of the touch screen device 5. In other words, these hard buttons execute their respective control functions without the user having to navigate through control menus, or without the touch screen device 5 being involved in any way.

Other of the hard buttons 31, 32, 33, are user configurable to control various external devices (e.g., stereo, temperature, light dimmer, etc) and/or system control functions. In some embodiments, one or more of the other hard buttons are programmed to interact with a graphical user interface displayed on the touch screen device 5, or control another application executing on the touch screen device 5.

The second application component provides the optional graphical user interface displayed on the touch screen device 5, and includes soft buttons used for controlling additional components, devices, and/or functions. The second application component also receives input (digital signals from hard button actuation) from the first application component and transmits the status of the actuated hard button (e.g., pressed) and/or control instructions to the automation system or to a particular external device in communication with the automation system via a wired or wireless communication link. The second application component also returns response/status signals (via the docking connector 12) that are used to control (i.e., turn on/off) the indicator lights 34 disposed on the enclosure 1.

In one embodiment, during an initial device configuration and set-up operation, the enclosure 1 is seated in, and in communication with, the docking station 2. The processor 50 then controls the USB switch 42 to establish a communication link between the processor 50 and the external docking connector 21. In this configuration, the processor 50 communicates with an external computing device (not shown) through the docking connector 21 and the docking station 2. This external computing device initially loads the first and second application components into memory 43. Thereafter, the processor 50 controls the switch 42 to establish a communication link between the processor 50 and the internal docking connector 12. The processor 50 then installs the second application component on the touch screen device 5. In other embodiments, the second application component is installed directly onto the touch screen device 5 by means known to those skilled in the art.

In normal wireless operation/mode (i.e., the enclosure 1 is not disposed in the docking station 2), the enclosure 1 is powered by the power supply 45. Further, the processor 50 controls the USB switch 42 to establish the communication link between the processor 50 and the touch screen device 5 via the internal docking connector 12.

When a user wishes to control a function of a device that is in communication with the automation system 70, such as muting the audio of the home theater 77, for example (see FIG. 4), the user simply presses the appropriate hard button 31, 32, 33 that is dedicated to, or programmed for, muting the audio. The processor 50 executing the first application component captures and transmits the digital signal corresponding to the mute audio command created by the user pressing the mute hard button (e.g., hard button 31 or 32) to the touch screen device 5 (via the connector 12). The second application component transmits the mute audio command via a wireless communication link (e.g., wireless Wi-Fi gateway 76) to the automation system 70, which in turn transmits the mute audio command to the home theater 77.

Upon receiving the mute audio command, the home theater mutes the audio and transmits a response or status signal to the automation system 70. The automation system 70 then wirelessly transmits the response signal to the touch screen device 5 via the wireless Wi-Fi gateway 76. The second application component executing on the touch screen device 5 transmits the response/status signal to the first application component executing on the processor 50. The processor 50 uses the received response/status signal to illuminate an indicator light 34 corresponding to audio muting being activated.

In normal wired operation/mode, the enclosure 1 is disposed in the docking station 2 and powered by an external power supply. Further, the processor 50 controls the USB switch 42 to establish the communication link between the processor 50 and the external USB docking connector 21. In this configuration, the processor 50 executing the first application component bypasses the touch screen device 5 and communicates directly with the automation system 70. In other words, all commands from the enclosure 1 are transmitted directly (via the docking connector 21) to the automation system 70. Likewise, all response signals are transmitted directly to the processor 50. Consequently, the enclosure 1 is capable of controlling external devices even if the touch screen device 5 is turned off.

In diagnostic mode, the processor 50 controls the USB switch 42 to establish a communication link between the processor 50 and the external docking connector 21. In this configuration, the processor 50 communicates with an external computing device (not shown) through the docking connector 21. This external computing device emulates the operation of the second application component, which normally executes on the touch screen device 5. In this configuration the digital signals transmitted by the processor 50 can be observed and first application component can be debugged.

Referring to FIG. 7, in another embodiment, an illustrative block diagram of the electronic components disposed in the clam shell enclosure 1 is shown. The electronic components disposed in the clam shell enclosure 1 include a processor 51, an authentication coprocessor 41, the memory 43, the USB switch 42, a power supply 46, a power over Ethernet (POE) interface 44, the external USB connector 13, an external docking connector 21′, which includes connections for Ethernet communication and power, and the internal docking connector 12, which includes connections for USB communication and power.

The processor 51 includes general purpose input/output (GPIO) interfaces that are in communication with one or more keypad matrices, which are in communication with the hard buttons 31, 32, 33. The processor 51 further includes a USB interface in communication with the USB switch 42 via a USB wired connection 131. The processor 51 further includes an inter-integrated circuit (I²C) (i.e., a digital bus) in communication with the authentication coprocessor 41 described below. In other embodiments, the USB interface on the processor 51 is a USB on-the-go (USB-OTG) interface.

The processor 51 still further includes a fast Ethernet channel (FEC) in communication over the FEC wired connection 431 with the POE interface 44, which is in communication with the power supply 46 and the external docking connector 21′. When the external docking connector 21′ is connected to the docking station 2, the POE interface 44 allows the processor 51 to communicate with an external device over an Ethernet connection.

The processor 51 is also in communication with the indicator lights 34 and the memory 43 (e.g., RAM, ROM, EPROM). In other embodiments, the processor 51 includes an on-board memory. The USB switch 42 is in communication with the internal docking connector 12 via a USB wired connection 133, and the USB connector 13 via a USB wired connection 132.

The power supply 46 includes a rechargeable battery and a charging circuit known to those skilled in the art and supplies power to all the circuitry disposed in the clam shell enclosure 1. When the enclosure 1 is disposed in the docking station 2, the POE interface 44 allows current from the Ethernet connection to pass to the power supply 46 and charge the battery therein. The POE interface 44 also allows current from the Ethernet connection to pass to the touch screen device 5 (via the internal docking connector 12) to charge a battery disposed therein. Further, the power supply 46 can also draw power from the battery disposed in the portable touch screen device 5 (through the internal docking connector 12) to charge the battery in the power supply 46 and supply power to the circuitry disposed in the clam shell enclosure 1.

The external USB connector 13 functions as a diagnostic port. When the second application component residing and executing on the touch screen device 5 needs to be installed, updated, or debugged, an external diagnostic computer is connected to the external USB connector 13, and the processor 51 switches the USB switch 42 to establish a connection between the external diagnostic computer and the touch screen device 5 (through the internal docking connector 12). The external diagnostic computer can then install or update the second application component. The external diagnostic computer can also emulate the signals produced by the hard buttons 31, 32, 33 and the first application component executing on the processor 52 in the enclosure 1, and transmit these signals to the touch screen device 5, and receive responses from the touch screen device 5. In this way, the second application component can be debugged.

The authentication coprocessor 41 is an encryption chip licensed from Apple, Inc., that is included in devices that are officially licensed to communicate with Apple® products. Consequently, if the portable touch screen device 5 were an Apple® iPad™ or Apple® iPod™, then the enclosure 1 would need an authentication coprocessor 41 to function correctly with the iPad. In operation, after the portable touch screen device 5 (i.e., iPad) and the clam shell enclosure 1 were connected together (via the internal docking connector 12), the portable touch screen device 5 would interrogate the clam shell enclosure 1 to verify (by communicating with the authentication coprocessor 41) that the enclosure 1 was a product officially licensed to communicate with the portable touch screen device 5. In this embodiment, the external USB connector 13 functions as a sync port through which the iPad or iPod can sync with Apple® iTunes™.

In one embodiment, during an initial device configuration and set-up operation, the enclosure 1 is seated in, and in communication with, the docking station 2. In this configuration, the processor 51 communicates with an external computing device (not shown) through the docking connector 21′ and the docking station 2. This external computing device initially loads the first and second application components into memory 43. Thereafter, the processor 51 controls the switch 42 to establish a communication link between the processor 51 and the internal docking connector 12. The processor 51 then installs the second application component on the touch screen device 5.

In another embodiment, the processor 51 can control the USB switch 42 to establish a communication link between the internal docking connector 12 and the external USB connector 13. In this configuration, the touch screen device 5 communicates with an external computing device (not shown). This external computing device installs the second application component onto the touch screen device 5. In still another embodiment, the second application component is installed directly onto the touch screen device 5 by means known to those skilled in the art.

In normal wireless operation/mode (i.e., the enclosure 1 is not disposed in the docking station 2), the enclosure 1 is powered by the power supply 46. Further, the processor 51 controls the USB switch 42 to establish the communication link between the processor 51 and the touch screen device 5 via the internal docking connector 12.

When a user wishes to control a function of a device that is in communication with the automation system 70, such as muting the audio of the home theater 77, for example (see FIG. 4), the user simply presses the appropriate hard button 31, 32, 33 that is dedicated to, or programmed for, muting the audio. The processor 51 executing the first application component captures and transmits the digital signal corresponding to the mute audio command created by the user pressing the mute hard button (e.g., hard button 31 or 32) to the touch screen device 5 (via the connector 12). The second application component transmits the mute audio command via a wireless communication link (e.g., wireless Wi-Fi gateway 76) to the automation system 70, which in turn transmits the mute audio command to the home theater 77.

Upon receiving the mute audio command, the home theater mutes the audio and transmits a response or status signal to the automation system 70. The automation system 70 then wirelessly transmits the response signal to the touch screen device 5 via the wireless Wi-Fi gateway 76. The second application component executing on the touch screen device 5 transmits the response signal to the first application component executing on the processor 51. The processor 51 uses the received response signal to illuminate an indicator light 34 corresponding to audio muting being activated.

In normal wired operation/mode, the enclosure 1 is disposed in the docking station 2 and powered by an external power supply. In this configuration, the processor 51 executing the first application component bypasses the touch screen device 5 and communicates directly with the automation system 70 via the Ethernet connection on the external docking connector 21′. In other words, all commands from the enclosure 1 are transmitted directly (via the docking connector 21′) to the automation system 70. Likewise, all response signals are transmitted directly to the processor 51. In this configuration, since controlling the external device does not involve using the touch screen device 5, the enclosure 1 can control the external device even if the touch screen device 5 is turned off.

Alternatively, the processor 51 can control the USB switch 42 to establish the communication link between the processor 51 and the external docking connector 21′. In this configuration, the processor 51 and the touch screen device 5 function as described above with respect to normal wireless mode.

Referring to FIG. 8, in still another embodiment, an illustrative block diagram of the electronic components disposed in the clam shell enclosure 1 is shown. The electronic components disposed in the clam shell enclosure 1 include a processor 52, the authentication coprocessor 41, the memory 43, the USB switch 42, a power supply 65, a Zigbee interface 64 in communication with a Zigbee antenna 63, the USB connector 13, the internal docking connector 12, which also includes connections for USB communication and power, and an external docking connector 21″, which includes connections for power.

The processor 52 includes general purpose input/output (GPIO) interfaces that are in communication with one or more keypad matrices, which are in communication with the hard buttons 31, 32, 33. The processor 52 further includes a USB interface in communication with the USB switch 42 via a USB wired connection 131. The processor 52 further includes an inter-integrated circuit (I²C) (i.e., a digital bus) in communication with the authentication coprocessor 41. The processor 52 still further includes a serial peripheral interface (SPI) in communication with the Zigbee interface 64. In other embodiments, the USB interface on the processor 52 is a USB on-the-go (USB-OTG) interface.

The processor 52 is also in communication with the indicator lights 34 and the memory 43 (e.g., RAM, ROM, EPROM). In other embodiments, the processor 52 includes an on-board memory. The USB switch 42 is in communication with the internal docking connector 12 via a USB wired connection 133, and the USB connector 13 via a USB wired connection 132. The authentication coprocessor 41 and the external USB connector 13 both function as previously described above with respect to the embodiment shown in FIG. 7.

The power supply 65 includes a rechargeable battery and a charging circuit known to those skilled in the art and supplies power to all the circuitry disposed in the clam shell enclosure 1. When the enclosure 1 is disposed in the docking station 2, current passes to the power supply 65 (via connector 21″) and charges the battery therein. Current also passes to the touch screen device 5 (via the internal docking connector 12) to charge a battery disposed therein. The power supply 65 can also draw power from a battery disposed in portable touch screen device 5 (through the internal docking connector 12) in order to recharge the battery (in power supply 65) and supply power to the circuitry disposed in the clam shell enclosure 1.

In the embodiment shown in FIG. 8, a wired connection to the automation system 70 is not envisioned. Therefore, during the initial device configuration and set-up operation, an external computing device (not shown) wirelessly communicates (via the Zigbee gateway 76′) with the processor 52 (via the Zigbee interface 64) to load the first and second application components into memory 43. Thereafter, the processor 52 controls the USB switch 42 to establish a communication link between the processor 52 and the internal docking connector 12. The processor 52 then installs the second application component on the touch screen device 5.

In another embodiment, the processor 52 can control the USB switch 42 to establish a communication link between the internal docking connector 12 and the external USB connector 13. In this configuration, the touch screen device 5 communicates with an external computing device (not shown).

In still another embodiment, the second application component is installed directly onto the touch screen device 5 by means known to those skilled in the art.

In normal wireless operation/mode (i.e., the enclosure 1 is not disposed in the docking station 2), the enclosure 1 is powered by the power supply 65. Further, the processor 52 controls the USB switch 42 to establish the communication link between the processor 52 and the touch screen device 5 via the internal docking connector 12.

The second application component transmits the mute audio command via a wireless communication link (e.g., wireless Wi-Fi gateway 76) to the automation system 70, which in turn transmits the mute audio command to the home theater 77. Upon receiving the mute audio command, the home theater mutes the audio and transmits a response or status signal to the automation system 70. The automation system 70 then wirelessly transmits the response signal to the touch screen device 5 via the wireless Wi-Fi gateway 76. The second application component executing on the touch screen device 5 transmits the response signal to the first application component executing on the processor 52. The processor 52 uses the received response signal to illuminate an indicator light 34 corresponding to audio muting being activated.

In another embodiment, the processor 52 executing the first application component captures and transmits the digital signal corresponding to the mute audio command directly to the automation system 70 via the Zigbee interface 64 and the wireless Zigbee gateway 76′.

The processor 52 uses the received response signal to illuminate an indicator light 34 corresponding to audio muting being activated.

In still another embodiment, the processor 52 executing the first application component captures and transmits the digital signal corresponding to the mute audio command directly to the automation system 70 via the Zigbee interface 64 and the wireless Zigbee gateway 76′.
